SPECIFICATION forming part of Letters Patent No. 539,119, dated May 14, 1895.

Application led July 30, 1894. Serial No. 519,047. (No model.)

To all whom it mayyloonoern: l

Be it known that I, JOHN COLLIS, a citizen of the United' States'of America, residing at Des Moines, in the county of Polk and State of Iowa, have inventedan Improved Steam- Pipe Sleeve, of which the following is a speciication. l Y l My object is to provide a sleeve that is complete in two parts that can be extended through a ceiling and below it in such a manner that it can be adjusted in length, after the ceiling is plastered, to produce a neat finish around a steam-pipe at the bottom of the ceiling, and l accomplish the results contemplated by the invention hereinafter set forth, pointed out in my claims and illustrated in the accompanying drawings, in which- Figure 1 is a view of the complete device ready to be applied. Fig. 2 is a section of a floor and ceiling, showing the device in section and in position as required for practical use. Fig. 3 is a bottom view of the flanged lower end of the sleeve that is adapted to be adjusted relative t0 theceiling after the plastering is finished.

A represents the top of the sleeve -in 'the form of a cast metal collar that has an annular flange adapted to overlie a floor It has perforated ears, b and b', through which rivets are passed for fixing jointly thereto a sheet metal sleeve section O and. metal strips d and CZ. It also has a perforated'lug f projecting upward and a set screw therein adapting theV complete device to be clamped fast to asteam pipe and suspended in proper position between joints before a floor is laid upon the joists. When a sleeve is not connected with this flanged collar A it can be advantageously used to cover the opening in a floor around the steam pipe because it is readily fastened to the pipe in such a manner that it can be raised from the floor 1andsuspended by the pipe while laying the iloor or making repairs. After a lloor islaid and supports the flanged sleeve section or collar A, I disconnect the collar from the steam pipe and break off the lugf. The collar and complete sleeve will then not be affected by any expansion or movement of the steam pipe.

H is a cast metal sleeve section that has an integral flange H2 adapted to overlie the plaster around a steam pipe as required to produce a neat finish.l It also has perforated ears, 7c and 7c', through whichrivets are passed for yxing thereto the lower end of a sheet metal section O2 that is telescopically connected at its/top end 4with the lower end of the mating section C fixed tothe cast metal. top A. It also has slots marked Z and Z, at its lower and partially closed end, through 6o which the free ends of the metal straps dand d are extended downward.

m and m are integral projections at the sidesof the slotsZ and Z', and fn and n are lstuds on said -projections adapted for connecting the metal straps therewith. The said straps are provided with perforations adapted to admit the said studs as hereinafter stated.

In applying the complete sleeve it is obvious it can be suspended by clamping the top V7o A to a steam pipeextended therethrough by means of the lug f and a set screw, or by letting the annular' flange of the top rest upon a floor, as shown in Fig. 2.

`The flanged sleeve section H suspended by 7 5 means of the perforated straps d and d, detachably and adjustably connected with the studs n and n', can readily be lowered so that the flange H2 will allow the ceiling to be plastered around the steam pipe when it can be 8o elevated to cover the plastering around the pipe, as shown in Fig. 2, and retained there by means of the metal straps that extend down through the slots l and Z to be connected with the lugs 'n and n. After the 85 sleeve is thus placed and adjusted the lower free ends of the metal straps ol and d are cut off and the work is finished.

It is obvious the top A, having a perforated lugf, can be used advantageously with- 9o out connecting a sleeve therewith.

It is also obvious the collars A and H can be connected to overlie the floor and the ceiling without combining the sheet metal sleeve section C and O2 therewith,

I claim as my inventionf l.` An improved steam-pipe sleeve comprising atop piece having an annular flange, a sheet metal sleeve section fixed thereto to extend downward, a second and mating sheet Ico metal section telescopically connected with the first named sheet metal section, a cast metal tube section having an annular fiange and slots in its bottom and studs below the e beanie slots fixed to the lower endof the second sheet metal section, and perforated metal strips fixed to the top piece and extended down through said slots and adjustably connected 5 with said studs; all arranged and combined to applyin the manner set forth for the purposes stated.

2. An adjustable sleeve for steam pipes comprising a cast metal section or collar havj 1o ing an annular ange adapted to overlie a iioor and downwardly projecting perforated ears for connecting .a sheet metal sleeve and metal strap therewith, a sheet metal section connected to the said perforated ears, a second 15 sheet metal section telescopicall y connected with the rst named sheet metal section, a cast `metal section having an annular flange adapted to overlie a `ceiling and the `bottom portion of the section contracted and provid-ed 2c with slots, metal straps fixed to the perforated ears of the section at the top and extended down through the said slots in the lower or bottom section and fastened tolhelowersection, and means for fastening the top section, or collar to a steam pipe all arranged and combined to operate in the manner set forth for the purposes stated. j

3. The combination of a collar having a horizontal flange adapted to rest upon a floor,

means for clamping the collar fast to a steam JOHN COLLIS.
